Redirect using cookie

[JayVee]

How would I go about rewriting this php in javascript? Its a simple cookie check with a redirect based on cookie value.

 

else if (!isset($_COOKIE['legal'])) { 
	header("Location: /index.php");   
}
	else 
if($_COOKIE['legal'] == "no"){
	header("Location: /index.php");   
}

if(document.cookie.length > 0 && document.cookie.substr(0, document.cookie.indexOf("=")) == cname) {
   if(document.cookie.substr(document.cookie.indexOf("=") + 1) == "no") {
      location.href = "index.php";
   } else {
      // cookie data was something other than no
   }
} else {
   location.href = "index.php"; // cookie wasn't set
}

 

I *think* that would do assuming the cookie format is just cname=no.  Things to lookout for are indexOf is case sensitive, and it returns -1 if the match string isn't found.
